DISPENSING APPARATUS.

Application filed November To all whom it may concern:

Be it known that I, J osnrn MoGmNrooK, a citizen of the United States ofAmerica, and a resident of Chicago, county of Cook, and State ofIllinois, have invented a new and useful Improvement in DispensinApparatus, of which the following is a specification. a

The main objects of this invention are to provide a dispensing apparatusof that character with improved means for pressing the contents of thereceptacle down toward and into the delivery mechanism; to provideimproved mechanism for automatically arresting the action of thepressure means when all of the contents have been removed from thereceptacle; and to provide means of this kind which is positive inoperation and comparatively simple in construction.

An illustrative embodiment of this invention is shown in theaccompanying drawings, in which- Figure 1 is a front elevation of adispensing apparatus of the type shown in the aforesaid applicationequipped with pressure feeding means constructed in accord ance withthis invention.

Figure 2 is an enlarged fragmentary sectional detail of the part of themechanism which controls the operation of the pressure feeding means.

Figure 8 is an enlarged detail view of the pawl which engages thepressure plate rack. A Figure t is a perspective view of the latch whichholds the rack as it is shifted downwardly.

Figure 5 is a perspective view of the cam by means of which the pawl isreciprocated.

Figure 6 is a detail view of the upper end of the pressure plate rack.

A dispensing apparatus constructed in accordance with this inventioninvolves the use of a supporting housing, within which is placed areceptacle in an inverted position from which the contents are forcedout into a delivery mechanism by a pressure plate gradually moveddownwardly, by the operating mechanism, until it reaches the bottom ofthe receptacle whereupon it is released from being further acted upon bysaid operating mechanism.

In the specific embodiment herein shown, the dispensing apparatuscomprises a supporting frame A, adapted to receive a speciallyconstructed removable receptacle B,

from which the contents are adapted to be forced into the deliverymechanism C, through the action of a feeding mechanism D controlled byan operating mechanism E.

Referring to the drawings, the supportin g frame A includes a tripod 1upon which is mounted a platform 2 and a housing 3 for the receptacle Band above which project the uprights 41-, affording a support for thefeeding mechanism D. Extending between the legs of the tripod l is across brace 5 near the bottom, and a shelf 6 about half way between thebrace and the platform 2. I-linged to the front edge of the shelf is aledge 7 for supporting a suitable container (not shown) in position toreceive the product as discharged by the delivery mechanism G.

The platform 2 is substantially circular in form, and is provided with asuitable opening (not shown) affording communication between thereceptacle B and the delivery mechanism 0.

The housing 3 comprises a pair of semicylindrical sect-ions 16 and 17having domeshaped tops. The section 16 is rigidly mounted on theplatform 2 whereas the section 17 is hinged to one of the uprights 1- soas to permit it to be swung back to allow the receptacle with itsfeeding mechanism D to be readily placed upon and removed from thesupporting frame A. The top of the section 16 has a latch 19 forengaging a pin 20 on the section 17 and locking the hinged section inits closed position.

The uprights 1 are in the form of tubes and are screwed. into orotherwise secured to the platform and connected at their up per ends bya member 22, and intermediate their ends by a brace or bracket 23. Themember 22 is disk-shaped and arranged to coact with a hood 2st toprovide a housing for a gear connected to the operating mechanism. Thebracket 23 has its middle part constructed to provide a housingembracing the rack 25 of the feeding mechanism D. This housing is madeup of two complementary parts 26 and 27, the former of which ispreferably integral with the remaining part of the bracket and thelatter of which is hinged at 28 so as to be swung into and out ofposition to coact with the part 26 to embrace the said rack Thereceptacle B is in the form of a specially constructed can, theseu'ii-plasi'iii-
